摘要： In an apparatus for measuring an oxygen saturation in blood, a plurality of light emitters irradiate a living tissue with a plurality of light beams having different wavelengths. A light receiver receives the light beams reflected from or transmitted through the living tissue to generate pulse wave signals in accordance with pulsations of the blood in the living tissue. A separator separates each of the pulse wave signals into a plurality of amplitude signals each of which is associated with one frequency, thereby generating pairs of amplitude signals each of which is associated with one of a plurality of frequencies. A first processor calculates a ratio between the amplitude signals in each of the pairs of the amplitude signals. A selector selects one of the pairs of the amplitude signals. A second processor calculates the oxygen saturation from the ratio of the selected pair of the amplitude signals.

摘要： A rotational position sensor having a compact and simple structure, in which a magnetic surface can be formed to have a more accurate shape, and an electronically controlled throttle device for an internal combustion engine, which employs the rotational position sensor. The rotational position sensor comprises a pair of substantially half disk-shaped magnetic cores disposed in an opposed relation to each other with a magnetic sensitive device interposed therebetween, a pair of substantially arc-shaped magnetic cores disposed in an opposed relation to each other along outer peripheries of the half disk-shaped magnetic cores, and a permanent magnet fixed in contact with at least one of the arc-shaped magnetic cores. Magnetic flux generating from the permanent magnet flows successively through one of the arc-shaped magnetic cores, the half disk-shaped magnetic cores, and the other of the arc-shaped magnetic cores, followed by returning to the permanent magnet. The half disk-shaped magnetic cores or the permanent magnet is rotatable, and the magnetic sensitive device detects an amount of the magnetic flux varying with rotation of the half disk-shaped magnetic cores or the permanent magnet.
